I am a 34 yr old male, I am taking atenelol 25 mg twice a day, Androgel 1.62 % one pump per day and 12 mg of zoloft once a day i am starting back on my zoloft, I am 210 lbs 5'7" i use to weigh 265 lbs and i lost the weight in a year, i use dip tobbacco, i drink one beer a day, i drink alot of sweet tea,water and an occasional frappaccino or coffee, no sodas. im mostly stressed out and i have anxious symptoms i rarely get the flutter in my chest and racing heartbeat anymore. i do get these symptoms im about to describe on occasion, sometimes once a day for a couple of days or sometimes twice a day for a week or two, then i can go weeks of months without having any of these symptoms , I get this thump in my chest and at the same time (simultaneously) i feel either dizzy or a freakout anxious type feeling it last as long as the thump does and goes away as soon as it does too( a couple of seconds if that), and other times it will be a bubbly flutter type feeling in the center of my chest and the same (simultaneous) time i will get that weird dizzy anxious feeling then just as soon as it starts the feeling will go away the same time it stops, i will also feel a little drained or tired after this happens, sometime it all happens so fast i cant get a grasp on how it exactly feels, its almost like the begginning of the freakout phase of a panic attack it is weird, i had a holter moniter and a ekg done years ago and it was normal, my doctor says its PVC's but im not so sure, is this serious should i be worried can someone help?
